What two numbers multiply to -663 and add up to -22?

Here we answer the question: "What two numbers multiply to -663 and add up to -22?"

The answer to your question is:

-39 and 17

Below we illustrate and prove that -39 and 17 multiply to -663 and add up to -22:

-39 × 17 = -663
-39 + 17 = -22

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² - 22x - 663 = 0

If so, the solution to factor the quadratic equation above is:

(x - 39 ) (x + 17)

To summarize, since -39 and 17 multiply to -663 and add up -22, you know that the following is true:

x² - 22x - 663 = (x - 39 ) (x + 17)
